    who traps 104+ with BASIC bolt ons?

    Complete list of mods, in chronological order, can be found HERE. At the time of that run, I was using stock control arms, springs, shocks, and struts. Chassis mods consisted of removed front swaybar, air bag in passenger side spring, rear-mounted trunk, and 26x8 Goodyear slicks. Bob

    who traps 104+ with BASIC bolt ons?

    Been a long time since I posted over here. Anyway, just to be accurate, what I claim as my best trap speed with the stock longblock is below: I did have one run in which I went 108.32 mph, but if you look at the car in the other lane, his mph was EXACTLY the same, and I didn't normally...

    Why 4.6?

    Agree totally with the above.

    Why 4.6?

    Ok. Quick question for you. You have two engines choices to put in your car. Here are the quick and dirty specs - make a choice. Engine A displaces 4L, makes 300 HP @ 5000 rpm (75 HP/L), is 30" wide, 30" tall, and 30" long. It weighs 600 lbs, fully dressed. Engine B displaces 5L...

    Why 4.6?

    Errr....I meant to put 21 mpg highway for the A4. Thanks for the correction - I edited my post.

    Why 4.6?

    I guess that depends upon your definition of "slightly less". A 2002 Z28 M6 was rated at 28 mpg highway. The same car with an A4 was rated at 25 mpg highway (regardless of gear). To go one further, the 2005 GTO (with the LS2 and .57 6th gear) is rated at 25 mpg highway, while the A4 is...

    Why 4.6?

    HP/L is a poor metric for determining how well an engine does. That's an arguement that the import racers have used for years, and is still virtually meaningless. A more useful measurement would be how much HP the engine makes vs how physically big and/or heavy it is. This is where the...

    Best aftermarket rear diff for a street car????

    If you're not going to race the car, the stock differential is fine. For an upgrade, I had (and highly recommend) a Truetrac differential. They redesigned them this summer (uses 3 pinions now instead of 2), and it performed flawlessly in my 99 Cobra Factory Stock car last year (high 1.5 60...

    My Engine is Out of My Car...All of the threads

    I'm very impressed (and somewhat surprised) that Ford is giving you a brand new car. However, it works out well for you, and in the end, likely for Ford too. Congrats, and best of luck to you. Bob

    Engine Dyno

    I have yet to hear of anyone dyno'ng a 3V 4.6 on an engine dyno, and I doubt anyone will anytime soon. There is very little reason to, and it isn't a cheap proposition. With few exceptions, magazines don't get cars and do that sort of thing. Rather, they find (or find out about) shops (or...

    05 gt or 02 ws6

    Can't imagine a DS making a significant difference. Torque Management certainly can, but I have no idea if it is/will/would. I would think that the average GTO will dyno about the same as the average C6. No reason not to.

    05 gt or 02 ws6

    I saw that - it made 351 RWHP, which is certainly believeable to me. As for Vettes and GTO drivetrain losses....I don't see where they would be much different, as both have the same tranny and an IRS.

    05 gt or 02 ws6

    The 05 Goat has 400 HP (probably 340 to 350-ish to the wheels), and will have no problems with an 05 GT. The 04 Goat has 350 HP (~300 RWHP), and given its extra weight, is a much closer race - easily within driver abilities (or lack there-of).

    05 gt or 02 ws6

    If an engine is run on the dyno with no accessories, that is what they used to do prior to ~1970 when ratings were "gross" HP. Today's "net" HP ratings are with all accessories on the car. That means if Chevy HiPo did this kind of test, it was not in line with how advertised HP is measured...

    Oh. Could you please post the link to them? I can't seem to find them. Better yet, you attached them to that post, so if you could just please attach them to your next reply to this post, that would work just fine. Thanks.

    No need. I'd prefer to see the pics you posted a few days ago, as it looks like you have deleted them. If you could please just post them again, that would be fine. Thanks.

    300HP? Thats It...Whats wrong with Ford

    Cool. When do you take delivery of your 2005 GTO? What color did you order? What did it cost you? I'm sure you have it ordered by now, right? Why did you get a 2002 GT when you could have had a much faster 2002 LS1 F-body? Why did you even bother registering on this site - just...
